Encrypted configuration files can be the provisioning server to

protect against unauthorized access and tampering of sensitive information (e.g., login

passwords, registration information). Yealink provides a configuration encryption tool

for encrypting configuration files. The encryption tool encrypts plaintext

<y0000000000xx>.cfg and <MAC>.cfg files (one by one or in batch) using 16-character

symmetric keys (the same or different keys for configuration files) and generates

encrypted configuration files with the same file name as before. This tool also encrypts

the plaintext 16-character symmetric keys using a fixed key, which is the same as the

one built in the IP phone, and generates new files named as <xx_Security>.enc (xx

indicates the name of the configuration file, for example, y000000000028_Security.enc

for y000000000028.cfg file). This tool generates another new file named as Aeskey.txt to

store the plaintext 16-character symmetric keys for each configuration file.

For a Microsoft Windows platform, you can use a Yealink-supplied encryption tool

"Config_Encrypt_Tool.exe" to encrypt the <y0000000000xx>.cfg and <MAC>.cfg files

respectively.

Note

Yealink also provides a configuration encryption tool (yealinkencrypt) for Linux platform

if required. For more information, refer to
